IMPROVEMENT IN LUBRlCATlNG-CUPS FOR STEAM AND OTHER ENGINERY.

Specification forming part of Letters Patent No. 86,009, dated January 19, 1869.

To all zc/wm it may concern:

4Re it known that I, l'sIDoRE DREYFUS, of the city and county of New York and State of New York, have invented a new and useful Automatic Steamlnjecting Lubricating-Cup; and I do declare the following to be a description, in full, clear, and exact terms, of the manner of making, constructing', and using the same, reference being had to the accompanying drawings making a part of this specilication.

My invention consists in devices, hereinafter described, for passing steam through a conduit until it reaches a deposit of lubricating material, a portion of which is continually discharged on that part of the machinery requiring lubrication, to effect which I cause a pipe conveying steam to terminate in a hollow tube, open at the top, which is firmly Xed in the inside of a cup or reservoir. At the side, and near the top of the tube, an opening is made.

Having placed the lubricating material in the cup or reservoir, a proper quantity of steam is injected, which, passing up the center of the tube, the proper pressure being applied, forces therequired quantity of lubricating material to pass from the cup or reservoir through the opening at the side of the tube, downward and inside from which it is led to a desired point.

The cup or reservoir, by preference, may be of glass, for reasons hereinafter stated, protected by a metallic covering to prevent breakage; but several openings are made on the sides of the covering, so that the person in charge of the machinery can see the quantity of lubricating material contained therein, and what pressure of steam to introduce in order to control the quantity of steam injected and the flow of lubricating material. A cock or valve is placed on the steam-supply pipe to regulate the injection of steam and to cut off the circulation when required. Another cock is placed at the side of the cup or reservoir to draw olf the water of condensed steam.

Referring to the drawing that accompanies i this specification, Figure l represents a complete cup or reservoir covered with brass with openings.

A is the steam-supply pipe B, the brass covering; C, the cock to regulate injection of steam; D, the cock to draw off water; E, the hopper into which the lubricating material is poured; F, the cock to regulate the supply of lubricating material; G, portions of the glass cup seen through the openings in the covering B.

Fig. 2 is a sectional view of Fig. l, showing the tube in the center. Fig. 3 is the tube, with its opening A at the top for the exit of steam, and the opening B for the entrance of the lubricating material.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The construction of the lubricating device substantially upon the principle and as herein described.

2. The combination of the cup G, tube H, and the other devices of the lubricating apparatus, whereby the circulation of steam in one direction through the tube H, and lubricating material in another direction through the same tube, is accomplished as herein set forth.

3. The arrangement of the steam-supply pipe A, cup G, covering B, cocks U D F, and tube H, substantially as described.
